Active Recombinant Human IFNA1 protein, His-tagged

Species :	Human
Source :	HEK293
Tag :	His
Protein Length :	24-189 a.a.
Form :	Lyophilized from 0.22 μm filtered solution in PBS, pH7.4. Normally trehalose is added as protectant before lyophilization.
Bio-activity :	Loaded Human IFN-alpha 1, His Tag on HIS1K Biosensor, can bind Human IFNAR1, Fc Tag with an affinity constant of 0.191 μM as determined in BLI assay (ForteBio Octet Red96e).Loaded Human IFN-alpha 1, His Tag on HIS1K Biosensor, can bind Human IFNAR2, Fc Tag with an affinity constant of 19.5 nM as determined in BLI assay (ForteBio Octet Red96e).
Molecular Mass :	This protein carries a polyhistidine tag at the C-terminus.The protein has a calculated MW of 21.3 kDa. The protein migrates as 22-24 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.
Proteinlength :	Cys24-Glu189
Endotoxin :	Less than 1.0 EU per μg by the LAL method.
Purity :	>95% as determined by SDS-PAGE.
Storage :	For long term, the product should be stored at lyophilized state at -20°C or lower.Please avoid repeated freeze-thaw cycles. This product is stable after at: -20°C to -70°C for 12 months in lyophilized state; -70°C for 3 months under sterile conditions after reconstitution.
Reconstitution :	It is recommended that sterile water be added to the vial to prepare a stock solution of 0.2 ug/ul. Centrifuge the vial at 4°C before opening to recover the entire contents.
